Abstract

Abstract A device of relatively simple construction for holding and latching a tape cartridge (or the like) is disclosed. The device comprises two spaced apart guide rails, one on each side of a recess for accepting a tape cartridge, whereby the guide rails serve to mate with corresponding grooves in the tape cartridge for receiving and guiding the cartridge into position. Two resilient biasing members are positioned adjacent the guide rails, in a one-to-one relationship, for acting against a common face of the cartridge to bias the cartridge against the guide rails. Each biasing member includes a projection for engaging a corresponding notch in the cartridge so as to inhibit the removal of the cartridge. The biasing members are contructed such that an appropriate movement of the cartridge results in the projections disengaging from the notches and allowing the cartridge to be removed (i.e. a separate release mechanism is not required).

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 181 words
A latching mechanism for a tape carrier, said mechanism characterized by: two spaced apart guide rails, having upper and lower surfaces thereon, one on each side of a recess for accepting a tape carrier, said guide rails serving to receive and to guide said carrier into position; two resilient biasing members positioned within the recess adjacent said guide rails, in a one-to-one relationship, for acting against a common face of said tape carrier to bias said carrier against said lower surface of the guide rails; each said biasing member being formed from a single piece of sheet metal and including a projection for engaging a corresponding notch in said tape carrier so as to inhibit the removal of said carrier; wherein movement adjacent a mouth of the recess of an inserted and latched tape carrier in a direction substantially perpendicular to the guide rails pivots said tape carrier against said lower surface of said guide rails so as to move said biasing members sufficiently to allow said projections to clear said notches and to thereby permit said carrier to be removed.
Claim 2
Dependent Claim 181 words
A latching mechanism for a tape carrier, said mechanism characterized by: two spaced apart guide rails, having upper and lower surfaces thereon, one on each side of a recess for accepting a tape carrier, said guide rails serving to receive and to guide said carrier into position; two resilient biasing members positioned within the recess adjacent said guide rails, in a one-to-one relationship, for acting against a common face of said tape carrier to bias said carrier against said lower surface of the guide rails; each said biasing member being formed from a single piece of sheet metal and including a projection for engaging a corresponding notch in said tape carrier so as to inhibit the removal of said carrier; wherein movement adjacent a mouth of the recess of an inserted and latched tape carrier in a direction substantially perpendicular to the guide rails pivots said tape carrier against said lower surface of said guide rails so as to move said biasing members sufficiently to allow said projections to clear said notches and to thereby permit said carrier to be removed.
Claim 3
Dependent Claim 22 words
The latching mechanism of claim 1 further including a resilient stop means for limiting the movement of said tape carrier upon insertion.
Claim 4
Dependent Claim 39 words
The latching mechanism of claim 1 wherein said biasing members are mounted in a cantilevered fashion with their fixed ends adjacent and within the mouth of the recess and their free ends, supporting said projections, remote from said mouth.
Claim 5
Dependent Claim 14 words
The latching mechanism of claim 3 wherein said tape carrier is a tape cartridge.
Claim 6
Dependent Claim 230 words
A cartridge latching mechanism, said mechanism characterized by: a pair of spaced apart guide rails having upper and lower surfaces thereon, straddling a recess for accepting a cartridge, said guide rails serving to receive and to guide said cartridge into position; a pair of resilient members positioned within the recess adjacnet said guide rails, in a one-to-one relationship, for acting against a common face of said cartridge in order to bias it against said lower surface of said guide rails, in s direction generally perpendicular to the direction of insertion of said cartridge; said resilient members being supported in a cantilevered fashion with their fixed ends adjacent and within a mouth of the recess and their free ends remote from said mouth; said resilient members being formed from a single piece of sheet metal and having a shape that results in the free ends of said resilient members being closer to said guide rails than said fixed ends, and said free ends each including a projection means for accessing a notch in said cartridge, wherein movement adjacent the mouth of the recess of the cartridge in a direction substantially perpendicular to the guide rails pivots said cartridge against said lower surface of said guide rails so as to move said biasing members sufficiently to allow said projections to clear said notches and to thereby permit said cartridge to be removed.
Claim 7
Dependent Claim 230 words
A cartridge latching mechanism, said mechanism characterized by: a pair of spaced apart guide rails having upper and lower surfaces thereon, straddling a recess for accepting a cartridge, said guide rails serving to receive and to guide said cartridge into position; a pair of resilient members positioned within the recess adjacnet said guide rails, in a one-to-one relationship, for acting against a common face of said cartridge in order to bias it against said lower surface of said guide rails, in s direction generally perpendicular to the direction of insertion of said cartridge; said resilient members being supported in a cantilevered fashion with their fixed ends adjacent and within a mouth of the recess and their free ends remote from said mouth; said resilient members being formed from a single piece of sheet metal and having a shape that results in the free ends of said resilient members being closer to said guide rails than said fixed ends, and said free ends each including a projection means for accessing a notch in said cartridge, wherein movement adjacent the mouth of the recess of the cartridge in a direction substantially perpendicular to the guide rails pivots said cartridge against said lower surface of said guide rails so as to move said biasing members sufficiently to allow said projections to clear said notches and to thereby permit said cartridge to be removed.
Claim 8
Dependent Claim 28 words
The cartridge latching mechanism of claim 5 further including a resilient stop means located remote from said mouth of said recess for limiting the movement of said cartridge.
Claim 9
Dependent Claim 77 words
The latching mechanism of claim 5 wherein each said resilient member is comprised of three generally planar areas: a first generally planar area for fixing said resilient member to a support means; a second generally planar area, bent out of the plane defined by said first planar area, toward said rails; and a third generally planar area, bent out of the plane defined by said second planar area, towards the plane defined by said first planar area.
